In my app I have a logout functionality. If user clicks logout it goes to home screen. Now I am exiting my app by pressing back button. But what I want is I need to exit automatically(i.e Programmatically) as same like as back button functionality. I know by calling finish() will do the functionality. But the thing is it goes to the previous activity.

Simply add finish(); in your first class' (login activity) onPause(); method. that's all
Sometimes is useful to override method onBackPressed() because in case you work with fragments and you're changing between them if you push backbutton they return to the previous fragment.
you can simply use onBackPressed();
or if you are using fragment you can use getActivity().onBackPressed()
You don't need to override onBackPressed()
- it's already defined as the action that your activity will do by default when the user pressed the back button. So just call onBackPressed()
whenever you want to "programatically press" the back button.
That would only result to finish()
being called, though ;)
I think you're confused with what the back button does. By default, it's just a call to finish()
, so it just exits the current activity. If you have something behind that activity, that screen will show.
What you can do is when launching your activity from the Login, add a CLEAR_TOP flag so the login activity won't be there when you exit yours.
Call onBackPressed
after overriding it in your activity.
